How do you interpret a moderation analysis?


How do you interpret a moderation analysis?

Moderation effects are difficult to interpret without a graph. It helps to see what is the effect of the independent value at different values of the moderator. If the independent variable is categorical, we measure its effect through mean differences, and those differences are easiest to see with plots of the means.

How do you describe the moderation effect?

A moderation effect means that the effect of a continuous independent variable (X; e.g., cognitive ability) on a continuous dependent variable (Y; e.g., academic achievement) depends upon the levels of a moderator (M: either categorical or continuous).

How do you know if mediation is significant?

If a mediation effect exists, the effect of X on Y will disappear (or at least weaken) when M is included in the regression. The effect of X on Y goes through M. If the effect of X on Y completely disappears, M fully mediates between X and Y (full mediation).

What does mediation analysis tell you?

Mediation analysis quantifies the extent to which a variable participates in the transmittance of change from a cause to its effect. It is inherently a causal notion, hence it cannot be defined in statistical terms.

How do you identify moderating and mediating variables?

Mediator vs Moderator Variables | Differences & Examples

  1. A mediating variable (or mediator) explains the process through which two variables are related, while a moderating variable (or moderator) affects the strength and direction of that relationship.
  2. You can think of a mediator as a go-between for two variables.

What is C prime in mediation?

The c path coefficient represents the total effect of the irrationality on the self-reported anxiety. The c-prime path coefficient refers to the direct effect of the irrationality on the self-reported anxiety.
